Pokemon Brilliant Diamond and Shining Pearl are remakes of the 2006 DS games. The Pokedex is a notable example of this, as Studio ILCA picked the original 151 Pokedex over the enlarged Platinum edition. The new Hideaways feature in BDSP allows Trainers to catch Platinum’mon early in the game. Here is a complete list of all Grand Underground Pokemon.

The Sinnoh Underground was technically present in the original Diamond & Pearl, Studio ILCA went to considerable measures to completely redesign it. Players can start catching powerful Pokemon as early as Eterna City.
